(See the best response by Kaiochao.)
Code:
obj/Block
    icon='Iso64.dmi'
    var/block
    Cross(mob/M)
        if(istype(M,/mob))
            if(M.dir == src.block)
                return 0
            else
                return 1
    Uncross(mob/M)
        if(istype(M,/mob))
            if(turn(M.dir,180) == src.block)
                return 0
            else
                return 1
    N
        icon_state="north";block=NORTH
    E
        icon_state="east";block=EAST
    S
        icon_state="south";block=SOUTH
    W
        icon_state="west";block=WEST


Problem description: Uncrossed() doesn't seem to be working as I'd expected. The goal here is to have one edge of the tile that you can not cross over. These would be laid over a fence for example, so that players can walk onto the tile containing the fence, but not walk through it.

What is actually happening?

Nothing. Say I put the obj/Block/N down, I can't cross onto that that location with a Northern direction, but I can with a Southern direction. Uncrossed() is supposed to stop me from leaving the location with a Southern direction (Opposite of the objects block variable), however it doesn't.

Edit: Now that I've looked at it some more, Uncrossed() is never called when I step off the object.

In my test environment, Cross() isn't being called either.

In mine, Cross() is being called, but Uncross() isn't. Odd.

Odd.

I just realised I've been writing Uncrossed() here and I use Uncross() in my code, my bad. The problem still exists though, Uncrossed() is useless as you can't block the movement after they have made it.

Cross/Uncross is definitely what you want to be using, not Crossed/Uncrossed. It's just strange that they're not working as expected, in a bare environment. You should probably file a bug report at this point, and refer to here.
